怎样分辨一个字母在不同的单词中的读音呢？【急需大家的帮助，回答好加分，很好的话加100分~~~】

Question

比方说，a可以读/ei/ /æ/ /ɑ: / /כ/ ，那怎样确定a在一个单词中到底读哪个音呢？
希望大家给出详细的答案，比如在后面有哪个字母时读哪个音。
最好是把26个英文字母的情况全部说出。万分感谢O(∩_∩)O
对了，是在不看音标的情况下~

Answer 1

恭喜你，你如果能这么想，已经在往正确读音的路上发展了，因为我也是这么过来的。我见过的很多孩子连想都不去想这些问题，只是在死记，而且觉得很痛苦。

我不得不说这个需要你自己进行积累，多读，多看，培养出 语感 你就能很明白自己在干什么了，

另外，其实读错也没什么的，看看音标就知道错哪了，只是要多读。

在非重读音节中，许多单词中的元音字母a e i 即可以读作[E]音，也可以读作音。

arar在[w]音后面 [α:] car farm dark sharpener
[C:] warm quarter towards
oror在[w]音后面 [C:] forty morning short
